Website projects

Websites we have just handed over.

Four live deployments — click and see for yourself. From lead generation for a factoring broker, through a craftsman's personal brand and a Viennese coffee house, to a multilingual demo of a booking system.

Portfolio

8 active products. Some are ours, some are under NDA.

Some run inside our own companies as SaaS. Some we build for clients who require anonymity. We will show you the competence — not their names.

Architecture

One platform. Many tools. Your data.

Instead of five generic SaaS tools billed every month — one system designed around your business. We bring every StudioApps product together into a single architecture.

  • 01

    Multi-tool platform

    Pulse + ContentOS + CRM + Lead Radar — one login, shared data, a single customer database. No duplicated SaaS accounts.

  • 02

    Self-hosted = your data

    Supabase / Postgres / S3 — all on EU servers that belong to you. Migration away from any provider in 14 days.

  • 03

    An extensible stack

    Next.js + TypeScript + Supabase. Your engineer can read it, modify it and extend it. No black box.

Technology stack

We choose boring technology on purpose.

We do not use the newest framework of the month. We choose what will still be stable in three years — Next.js, TypeScript, Postgres, Supabase.

Philosophy

Five things we believe.

01
Small on purpose

We write every line ourselves. A boutique studio, not an agency with account managers and subcontractors.

02
The products are the proof

We do not show faces. We show products with real numbers instead of references.

03
Transparent company data

KRS, NIP, REGON, registered address, GDPR, servers in the EU. In the footer. Always.

04
An engineer's language

Specifics, numbers, ROI. No "revolutionising", no "transforming", no "synergy".

05
Our clients require an NDA

Our clients do not want public case studies. We will show you everything under NDA on a call.

Manifesto

What we believe.

  1. Small engineering teams deliver better software than large agencies.
  2. A client deserves full control over their own data.
  3. One well-designed system replaces five generic SaaS tools.
  4. Transparency about numbers builds trust faster than marketing promises.
  5. Long-term partnership, not short-term delivery.
How working together looks

Three steps. No sales decks.

01

A call — 30 minutes

You tell us about the problem, we share our screen with systems that are already running and show real numbers. We say straight away whether we are the right fit.

02

Demo and quote

You get a concrete proposal: scope, timeline, price. If we have a similar system in the portfolio, you will see it live under NDA.

03

Start and first results

Small iterations, working software every week or two. No waiting months for a “big reveal”.

Let's talk

We will show you what we can do. Under NDA.

Send us a short message — we reply within one working day. The first call takes 30 minutes: a screen share of our systems and real numbers from real clients. No sales deck, no "advisers", no follow-ups every three days.

What you get on the call
  • Real numbers from real clients (under NDA)
  • A live demo of a chosen system from our portfolio
  • An honest verdict: whether we fit your problem at all
  • No sales pitch — you talk to engineers
